Pioneer Traktor Scratch Certifed Mixer

Pioneer have a 20 year history of designing high quality mixers for professional DJs, the DJM-850 does not disappoint. Featuring a high quality internal soundcard and 3 layers of quality Pioneer FX to help you shape your sounds and heighten the performance.

The DJM-850 incorporates a high quality USB soundcard that enables as many as four inputs/outputs simultaneously with no degradation in the sound and supports various sampling rates (96kHz/48kHz/44.1kHz)and the ASIO/Core Audio standards, making it ideal for music recording and production. The USB port on top of the mixer offers quick connection your computer. The output routing from the mixer can be easily modified using the setup utility tool once connected to a computer.

The DJM-850 is true to Pioneer’s traditional mixer layout, it features a variety of advanced sound effects, providing DJs with endless possibilities. The DJM-850 also includes new BEAT COLOR FX which change effects by linking the input sound from each channel.

The use of high quality components such as a 32-bit digital-to-analog output converter and a 32-bit digital signal processor, separate analog and digital circuitry, and extremely short audio transmission paths results in clear and powerful audio output.

Simple connection to Scratch Control (DVS) with TRAKTOR SCRATCH PRO Connect the DJM-850 to a PC to Scratch Control (DVS) with CDJ player and Vinyl using timecode disc bundled in TRAKTOR SCRATCH PRO.

  • MIDI Signal - Operation information of the mixer’s knobs and buttons can be transmitted as a MIDI signal for a “Full Ensemble MIDI” function to control other connected devices.
  • Switching 3 - Band EQ/Isolator - Each channel of the mixer is equipped with a switchable 3-band EQ (+6dB to -26dB) and 3-band isolator (+6dB to -∞dB)
  • High Performance Channel Faders - The slide mechanism supports the fader knobs with two metal shafts for both durability and smooth operation. Furthermore, the new mechanism’s design minimizes the negative effects of moisture or dust particles on the mixer’s performance.
  • P-LOCK Fader Cap - Keeps the fader channel and crossfader knobs (caps) locked, preventing them from physically slipping off during heavy use.
  • Scratch Control - Scratch Control* is possible by using the time code disk attached to DJ software supporting DVS (Digital Vinyl System) from CDJ players and vinyl turntables.
  • Auto Standby - Automatically senses inactive operation and the presence of input signals, switching to standby mode when inputs are not detected for a long period of time.
